These projections are PRELIMINARY. You must check back frequently to determine whether you have the most recent estimates. They are based on freely available international modeling group coupled climate models, and were contributed for the IPCC AR4 report. Thanks to the PCMDI archive for serving the models and to University of East Anglia for climate data. Last changed 12-21-2007 |

Local Sea Level Trend |
||
| Excel File - this variable is the model thermosteric sea level minus global instantaneous thermosteric sea level anomaly relative to present day. That is, adding this quantity to global sea level gives the total plus local changes due to regional heating or freshwater or mass adjustments. | ||

| Notes: | ||
- The points represent 20 year centered averages - error bars are based on the 25th and 75th percentile range of the model ensemble -Global A2 range is 21-53cm, so including the regional change would increase the range to: 26-58cm. - 7 out of 9 models have increases in their regional sea level anomalies. 3 models have increases greater than 10cm. -Landerer et al, 2007 attribute this increase to poleward migration of the North Atlantic Current. |
